Telescoping Illumination Attachment for Electrocautery Pencil

Solution Overview

Problem

Existing electrocautery pencils face challenges in illuminating the surgical field effectively due to shadows cast by the device and overhead lights, which can obscure the view for surgeons during procedures.

Innovation Solution

A compact illumination device with a light source positioned at the tip of the electrocautery pencil, powered by a battery and designed to telescope with extenders, reducing shadow issues and integrating smoke evacuation capabilities, allowing for improved visibility without the need for replacing the entire pencil or generator.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If overhead lights or lighted retractors are used to illuminate the surgical field, then the surgical field can be lit, but shadows are cast by the surgeon's hand or electrocautery device that obscure the surgical field

Engineering Contradiction:
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by placing the light source directly at the tip of the electrocautery device, providing localized illumination exactly where needed in the surgical field. This eliminates shadow problems by positioning the light source at the precise location where illumination is required, rather than using overhead or distant light sources that create shadows.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent introduces an intermediary light source that is attached to the electrocautery device itself. This intermediary light source acts as a mediator between the surgeon's needs for illumination and the requirement to avoid shadows, providing light from the optimal position without requiring separate overhead lighting systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Illumination intensity

If a light source is added to the electrocautery pencil, then illumination of the surgical field is improved, but the device complexity increases

Engineering Contradiction:
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent merges the illumination function with the existing electrocautery device by attaching a light source to the pencil. This combining of functions allows the electrocautery device to serve both its primary cutting/coagulation purpose and provide illumination, eliminating the need for separate lighting equipment and reducing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent makes the electrocautery device multi-functional by adding illumination capability to it. The device now serves dual purposes: performing electrocautery procedures and providing surgical field illumination, thereby reducing the need for additional separate devices and simplifying the overall surgical setup.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Illumination intensity

If the entire electrocautery pencil is replaced to add illumination, then illumination capability is achieved, but the cost increases and distribution becomes more difficult

Engineering Contradiction:
Core Design Contradiction:
Illumination intensityVSEase of manufacture

Solution Approach 1:

The patent segments the illumination function from the main electrocautery device body, creating a separate attachable light source component. This segmentation allows the illumination feature to be added as a modular attachment rather than requiring replacement of the entire electrocautery pencil, thereby reducing manufacturing costs and simplifying distribution logistics.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary attachment component that serves as a bridge between the existing electrocautery pencil and the light source. This intermediary piece allows compatibility with standard electrocautery devices without requiring complete replacement, reducing costs and facilitating easier distribution and adoption.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An illumination device for use with a standard electrocautery pencil is described, having a distal end capable of telescoping for use with cautery extenders. The illumination device also has a light source on the distal end to reduce shadow problems, and a tube is provided for evacuation of smoke from the surgical field. The device is sized to fit on any standard electrocautery pencil. The light-emitting component on the device reduces shadows and evacuates smoke from the treatment sight without necessitating purchase of a new electrocautery device.
